Abstract

The single point calibration method introduced by Hünemohr in 2014 is analysed in this study for DECT energies 90/150Sn kV. The composition of 38 calibration materials have been used to investigate, which predicts the relative electron number density and effective atomic number accurately. Also an optimal constant α has been determined to be 3.3. The best calibration materials have been used in calculating the relative stopping power for 81 human tissues. The calibration materials AlMgSi, Al2O3, Carbon, SB3, Methanol show less than 1 percent relative difference compared to the relative stopping power calculated from composition; KCl even showed less than 0.1 percent accuracy. This was a theoretical study, so an experimental one is needed to confirm these results.
